TEMPORARY BINDER.

Specification of Letters Patent.

Patented Apr. in, .1917.

Application filed November 11, 1915. Serial No. 60,972.

To all whom it may concern."

Be it known that I, EGMONT B. AnNoLo, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Temporary Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to the subject of temporary binders, and more particularly to the type of binders known as the fold engaging bar type.

The primary object of the invention is to produce a novel form of post for the foldengaging bar, the post being provided with means for locking the bar in engagement therewith, the locking means being of such a nature that it will firmly hold the bar in engagement with the post, yet can be readily manipulated by a suitable key or the like to release the bar.

Other and further objects of the invention will be apparent from the following detailed description and pointed out in the claims.

Referring to the accompanying drawings. in which one simple and practical form of the invention has been shWI1- Figure 1 is a vertical sectional view of a binder equipped with the improved means for locking the fold-engaging bar, the section being taken on the line 1-1. Fig. 2.

Fig. 2 is a sectional view taken on the line 2-2, Fig. 1.

Fig. 3 is a detail fragmentary view in elevation of the lock and bar.

The present invention has been shown in connection with the usual form of binder including the covers, back, and hinge post to which one end of the fold-engaging bar 1 is hinged, in any convenient or preferred manner. The locking post may be formed from a single strip of sheet metal. having its base suitably fastened to the inner surface of the backof the binder, the'post being designated by the numeral 2 and preferably is an integral right-angularly projecting outstanding portion of said base. The free end of the post 2 is outturned and rolled to form a housing 3 and said housing is provided with a central circumferential slot 4, the slot extending a short distance longitudinally of the post. Alock 5 is journaled. in the housing 3, said. lock having a head 6 that abuts one outer end edge of the housing 3 and has its other end enlarged or upset to form a flange 7 said flange 7 and the head cooperating, by on gaging the outer end edges of the housing, to prevent longitudinal movements of the lock within the housing. The lock 5 may be in the form of a bolt, cylinder, or any other suitable shape that will have a. snug, but

rotatable fit within the housing 8, and said lock has a central transverse slot 6 formed therein that forms a continuation of the slot in the housing 3 when the lock is rotated in one direction, but when rotated in another direction the lock will present an obstruction to a fold-engaging bar passing through-said slot in the housing, as will be explained. Any suitable expedient may be resorted to to effect the necessary turning movements of the lock 5, a convenient one being obtained by forming holes or openings 8 in the head 6 of said lock which may be engaged by a spanner or other tool or key, not shown.

The fold-engaging bar 1 may be of the usual or any other convenient form in-so-far as its hinged connection with the hinge post is concerned, but my present invention contemplates forming a notch 9 in the upper longitudinal edge of the bar adjacent the free end thereof, the notch being so formed that a hook 10 at the free end of the bar is provided.

In using the improved binder, assuming the bar 1 to be disengaged from looking post, the lock of said post is rotated to aline its slot 6 with the slot 4 of the housing 8, whereupon the free end of the bar 1 may be readily dropped through said alined slots and rest upon the base of the slot in the post 2, when by turning the lock 5, said lock will enter the notch 9, as shown in Fig. 2 of the drawings, and exert a downward pressure on the hook 10, sufficient to firmly hold the said bar to the base of the slot in post 2. A reversal of the movement of the lock 5, will cause the slots of the lock and post 2 to aline, whereupon the bar 1 is free and may be readily lifted from post 2, such lifting movement being permitted through the hinge connection of the bar with the hinge post.

The invention has been shown as consisting of but one fold-engaging bar, but it is to be understood that the same principles employed in connection with but one bar may be applied to binders that are equipped with more than one bar.

I claim as my invention 1. A temporary binder comprising 7 a hinged fold-engaging bar having a hook at its free end, a locking post provided With a. lock housing, a lock rotatable therein, said housing post and lock being complementally slotted for interlocking engagement With the hook of the bar.

2. A temporary binder comprising a looking post having an end housing, said post and housing being complementally slotted, ahinged fold-engaging bar having an end portion adapted to enter said slots, and a lock rotatable in the housing provided With a slot that permits the entrance of the bar and adapted to be rotated to prevent with draW'al of said bar.

3. A temporary binder comprising a hinged fold-engaging bar having an end portion of the bar, and means within the housing for preventing release of the bar from said slotted portion of the post and housing.

4. A temporary binder comprising a hinged fold-engaging bar, a locking post having a lock housing extending transversely of the outer end thereof, the housing being centrally circumferentially slotted and such slot being extended into the post, a locking bar rotatable in the housing and provided with means for permitting the free end of the bar to enter the slotted portion of the housing and post and with means for preventing release of said free end of the bar.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
